Code

18

Description

Fuser Error
(The number indicates the detailed error code) 0 The fuser did not become to the main motor driving temperature in 50 seconds after printing started. 1 The fuser did not become to the paper pick-up temperature in 50 seconds after printing started. 2 The fuser did not become to the main motor driving temperature in 30 seconds after warming up started. 3 The fuser did not become to the warm-up finishing temperature in 30 seconds after the motor started driving. 4 A temperature of 250°C or higher is detected in a mode other than sleep mode. 5 The fuser does not warm after fuser error is solved and the power is turned OFF/ON. 6 A low temperature of 10°C is detected in 10 seconds after printing started. 7 A temperature of 190°C is detected in ready mode after printing finished.

Remedy

1. Turn on the power again, and verify the fuser warms up. If it does not, see step 4. 2. Check the contact between Fusing thermistor and Connect A PCB(P89). 3. Check the contact between Connect A PCB (P80C) and the main board. 4. Replace the Fuser. 5. After replacing the Fuser, verify the fuser warms up when the power is on. 6. Replace the main control PCB.

The ballast board controls the bulb. It is the board with the wires going to the bulb socket. Replace that and you'll have a working projector.

No they are not noted for this type of problem. You may have a sticking air temperature control bleed door and/or a defective blend door actuator stepper motor

In such a situation it is best to dis- arm the alarm as it can give false signals and give you sleepless nights.
Even if the sensitivity is set to low it can cause alarm as when a large truck moves the vehicle.
Alternatively you can use the new generation alarm system with surveillance which can connect to a mobile phone if some one tries to enter your car.

Hi,

From the Xerox Phaser 4500 Service Manual (here), the main problems could be one of:

• Warm-up failure - Fuser warm-up not complete within 110 seconds after
• starting.
• Cool-down error - Cool-down process not complete within 200 seconds.
• Low trouble temperature - The fuser temperature drops to the low trouble
• temperature (approximately current control temperature, minus
• approximately 25°C).
• High trouble temperature - The fuser temperature rises to the high trouble
• temperature (approximately current control temperature, plus
• approximately 35°C).
• STS circuit open
• STS failure - The heat rod remains on for at least 10 seconds after warm-
• up has completed

It could be that your fuser needs to be replaced, but as you can see that code relates to a couple of problems, so even replacing the Fuser might not fix the problem.

If it doesn't even do the warm up checks it is likely to be the fuser because the other components such as STS failure and cooldown won't have had a chance to run..

These two problems can be related.
If the water temp is low, You are NOT going to get a good extraction (almost no crema).
wait like 20 min. before using the machine, And if there is a pressure gauge (on the machine) it has to be in the 1 to 1.2 range.

Always warm up the portafilter/handle before use.
If the water is hot and there no crema, Adjust the grinder.
The group temperature is about 212f for commercial espresso machines.

see if the back wall inside of freezer have ice if so you have to change tiker board or check your doors if closing

It is observed in branded printer not only lexmark also with HP printers yoou get this same problem.
It is always recomended to use genuine cartridges rather than refilled or any other brand ink cartridges.
As for HP cartridges they are all made under six sigma process where it is very rare you get a ink cartridge issue.
thats why HP Gives 18 months of replacement warranty on its cartridges
The same applies to Lexmark printers aswell
Make a habit of usig Genuine cartridges which will give value for your money.

I have just changed the fuser unit and the printer is still giving the
same error [fuser error and low heating] Kindly help.
